Description

Phosphoric Acid Di(2,3-Dibromopropyl) 2,3-Dichloropropyl Ester is a specialized organophosphorus compound engineered as a highly effective flame retardant additive. Its molecular structure, incorporating both bromine and chlorine, provides a synergistic mechanism for interrupting the combustion cycle in polymeric materials. This product is essential for manufacturers seeking to enhance the fire safety of their products while maintaining material performance. Key industries that rely on this compound include plastics, textiles, and construction materials requiring stringent flame-retardant standards.

Application

• Primary additive in flame-retardant polyurethane foams for furniture, mattresses, and automotive interiors.
• Synergistic component in flame-retardant formulations for engineering plastics such as ABS, polycarbonate, and epoxy resins.
• Imparting flame resistance to textile back-coatings and finishes for protective clothing, curtains, and upholstery fabrics.
• Used in the production of fire-safe cables and wires by compounding into PVC and other cable jacketing materials.
• Application in construction materials like flame-retardant paints, coatings, and sealants.
• As a reactive or additive flame retardant in certain adhesive and sealant systems.

Quality Control

Our production of Phosphoric Acid Di(2,3-Dibromopropyl) 2,3-Dichloropropyl Ester adheres to a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed against key parameters including bromine/chlorine content, acidity, and viscosity. Certificates of Analysis (COA) documenting purity and specification compliance are provided with every shipment. We support compliance with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Due to its properties as a strong oxidizer, isolate from reducing agents, organic materials, and other flammable substances. Recommended storage temperature is 15-25°C. Keep container tightly sealed when not in use to prevent moisture absorption.
